NCAR's Turbulence Numerics Team -- TNT

Turbulence refers to the complex behavior of fluid flow that
happens at many different scales and in many different physical
systems. One practical hallmark of turbulence is that small-scale
motion can organize into larger scale features, such as eddies or
vortices, and affect the flow at much larger scales.

The Turbulence Numerics Team (TNT) is complementary to the
Geophysical Turbulence Program (GTP)
and is focused on the
accurate simulation and understanding of turbulence for fluids,
such as the atmosphere and for charged flows in the presence of
magnetic fields. TNT research emphasizes simplified physical
systems that still reproduce the complexity and multi-scale
properties associated with turbulent flow.
